If I preview the page and click the play button, it will play in the page (not fullscreen) and there's the option to click on the fullscreen button. If I open the developer tools (in Chrome) and refresh the page, it will then work like I want it to. I click on the play button and it automatically opens in fullscreen mode and starts playing. Why will it only do this if I open the developer tools and refresh?

Does this have anything to do with the type of vimeo account that I'm getting the embed code from? I believe it's just the basic, free account.

Hopefully I'm explaining this right. Any help/suggestions are greatly appreciated.

I realize these videos are filling the window and not fullscreen, but I like the effect. I looked at the code and see that it's an embedded vimeo link, but I'm can't figure out how it's automatically filling the screen when it's clicked.
